84 Mr. D. A. Banuenuau on an Ornithological 



by the results. Bishop spent six days (June 19 -14) on 

 Allegranza and made a thorough report on the birds found 

 there ; he also supplied me with a useful sketch-map of 

 the island and took a number of photographs, from all of 

 which I have drawn up the following account. 



Allegranza. 



Situated 5^ miles due north of Montana Clara and 

 103 miles from the African mainland, Allegranza is the 

 extreme northerly member of the Canary group. Almost 

 round in shape the island is larger than Montana Clara, 

 being 2| miles long by 2^ broad, and having an area of 

 3f square miles. 



At the western end an immense extinct volcano — Montana 

 de la Caldera — rises to 940 ft., and on the south-east coast 

 two smaller craters rise abruptly from the sea. The rest of 

 the island is for the most part flat and consists of low hills, 

 lava slopes, and stony plains. 



The usual vegetation of the eastern islands is met with, 

 including low Euphorbia bushes with enoi-mously thick 

 stems. Here and there patches of wheat have been cultivated 

 on the plains, but for the most part the island is 

 unproductive. 



Allegranza possesses a lighthouse built on a low neck of 

 land on the extreme eastern point. Both from the Keeper 

 of this lighthouse and the Majordomo who looks after the 

 island for the owner^ my party received the greatest possible 

 kindness. 



Ornithologically Allegranza proved highly instructive, 

 for considering the isolated position which it holds, a 

 surprising number of apparently resident species were 

 recorded. The most noteworthy occurrence was^ of course, 

 that of the new Chat, but amongst other interesting species 

 may be specially mentioned Trjto flanimea (jracilirostris , Buteo 

 buteo insularum, and (Edicnemus cedicnemus insularum. 



Only one form of Petrel was found here — Pufflnns kuhli 

 tiavirusiris ; but, as in Graciosa, it seemed to monopolise 

 every hole and cave available.
